Magnetic storage device coating and process

ABSTRACT

THE MAGNETIC SURFACES OF MAGNETIC STORAGE DEVICES ARE PROTECTED AGAINST ABRASION AND FRICTION BY APPLYING A LUBRICATING COATING OF A PERFLUOROALKYL POLYETHER AND AN OPTIONAL THIN COATING OF A TRIFLUOROCHLOROETHYLENE COPOLYMER TO THE SURFACE THEREOF. THE PERFLUOROALKYL POLYETHERES EMPLOYED PREFERABLY HAVE A MOLECULAR WEIGHT OF AT LEAST 1000.
